Knowledge of Potassium Type Series Colloidal Silica
Potassium Type Series colloidal silica is a type of silica sol, a colloidal suspension of silica particles in a liquid, typically water. The "potassium type" refers to the type of cation (positively charged ion) present in the suspension, in this case, potassium. The "series" refers to the size range of the silica particles in the suspension. Colloidal silica is commonly used as a dispersant or thickener in various industrial and laboratory applications.
Colloidal silica/Silica sol is a kind of colloid which is formed by nm-grade particles SiO2, dispersed in water. It is odorless, tasteless and nontoxic and its chemical molecular formula is mSiO2·nH2O.
1. The colloid particles are minute, and the particle size can be controlled according to customers' requirements.
2. Colloidal silica/Silica sol has relatively large specific surface area, and high heat-resisting performance (1500-1600"C).
3. With low viscosity, it can soak the places where water soaks; therefore, it presents excellent dispersion and permeability.
4. When the moisture contained in silica sol is evaporated, the colloid grains firmly adhere to the material surface and the combination of silicon and oxygen is then formed between grains. It is a good adhesive.
Product application: coating, refractory industries, investment casting, polishing etc.
